摘要
介绍了利用物理相似模拟技术研究煤层底板突水机理的方法，实验表明完整底板破坏究水是沿“零位破坏”线发生的，底板断层交水与断层性质及采空区大小有着密切关系，并揭示了断层突水的机理，这说明用相似模拟技术研究底板究水机理有着重要价值。
The paper introduces the method by wich the water inrush mechanism is studied with the physical analog simulation technique. The experiments indicate that water inrush due to the destruction in intact floor is occurred along the'zero position destruction'line,the water inrush in floor fault is related closely to the nature of fault and the size of worked-out area. The mechanism of water inrush from the fault is revealed. It is indicate that the physical analog simulation technique has an important value in the study on the water inrush mechanism in floor.
